Aerial/Seagrass Update St. Lucie River also Lake Okeechobee 7-23-23

 

Today I share my husband Ed Lippisch’s aerial photographs and one video taken around 11:30am on 7-23-23. Also included in the post are photos of reemerging seagrass beds taken by my brother Todd Thurlow on 7-2-23. A wonderful thing although Todd estimates that just under 80 acres were in the area he visited.  

The St. Luice River/Indian River Lagoon is dark from rain, C-23 and C-24 discharge, and stormwater run-off, however most of the ocean looks gorgeous blue. You can even see the nearshore reefs. Seagrass and or macro-algae appear near the sandbars just inside the inlet. Not the 600 acres of yesteryear but some, and this is a good sign. There has been no discharge of Lake Okeechobee since April and that was a small amount with no algae. Nonetheless, it is never good for the river.

Lake Okeechobee shows no major algae blooms near S-308 as just a week ago at Port Mayaca although one can see the long green wisps like shadows in the water. This changes every day and you can follow at eyeonlakeo. This is Todd’s site and it shows Lake Okeechobee at 15 feet. Pray for no hurricanes.

There is algae on the inside gate of S-308 and some along the St. Lucie Canal also known as the C-44 canal as titled when it became part of the Central and South Florida Flood Control Plan of 1948. S-308 is overseen by the Army Corps of Engineers since 1930 but the South Florida Water Management District is involved spaying peroxide pellets on the algae when it gathers in big blue-green-gray rotting clumps as it did last week.  The algae dies but more than likely sinks releasing toxins. A conundrum most definitely….

Thank you to my husband Ed who is in his tenth year documenting our waters by air. All of working together are make a difference. We are watching and they know it.

Sailfish Flats between Sewall’s Point and Hutchinson Island – note seagrass and macro algae in dark waters.

Underwater one can see the macro-algae atop seagrass. Macro-algae is increasing due to nutrient pollution and warmer temperatures. 7-2-23, Todd Thurlow.
